Background
The plant is located on a reclaimed island off the western coast of the state of Perak, around 10 km south of Lumut and 288 km north of Kuala Lumpurin in the district of Seri Manjung.[1]
Units 1-3
The first 3 x 700 MW subcritical units of the plant were built in 2002 and 2003. They employed "a seawater scrubbing process for flue gas desulphurization".[2][3]
Unit 4
Unit 4 was expected to be the first ultra-supercritical coal plant in Southeast Asia. In 2012, the unit was under construction and scheduled for completion in 2015. It was planned to be 1,080 MW.[1]
Alstom reported that a 1,000 MW supercritical unit 4 was synchronized in September 2014,[4] although other reports noted that when the plant entered operation later in April 2015, it was 1,080 MW and ultra-supercritical.[5][6]
The boiler for Unit 4 was manufactured in Wuhan Boiler Company, a Chinese manufacturing facility of which Alstom acquired a 51 per cent stake in 2007.[7]
In December 2023, major boiler damage took Unit 4 of Manjung power station offline. The unit was still offline in February 2024, and repairs were projected to take through the end of the year.[8] In August 2024, the unit was still slated to be brought back online by the end of 2024.[9]
Unit 5
A contract was signed in August 2013 for construction of Unit 5, which was expected to begin in January 2014 and be completed by October 2017.[10]
In May 2017, it was reported the plant was planned for commissioning in October 2017.[11] Unit 5 was reported as operational in September 2017.[12]
Planned retirement
In February 2020 and March 2021, Malaysia's Suruhanjaya Tenega (Energy Commission) released generation development plans covering 2020-30 and 2021-39. Additional background is available at the Unnamed Malaysia coal projects wiki.
The plans forecasted retiring the original three Manjung power station units ("TNB Janamanjung (2,070 MW)") in 2030.[13][14][15]
In August 2022, TNB announced that they would be retiring selected coal plants earlier than planned and would be replacing the generation with renewable energy alternatives. The President and CEO of the firm stated: "TNB is very much in the driver’s seat when it comes to delivering the nation’s energy transition, and this responsibility is the impetus for TNB to accelerate our ESG initiatives". Subject to approval, the power stations initially targeted for early retirement were Jimah East power station, Sultan Aziz power station and Manjung power station.[16]
Possible co-firing in the plant's future
In May 2023, it was announced that feasibility studies were underway to assess options for co-firing biomass or ammonia with coal at the Manjung (Janamanjung) power plant. [17]
In October 2023, co-firing feasibility studies for hydrogen, ammonia, and biomass were "ongoing".[18]
Coal Ash Pond Conversion
In March 2022, Tenaga Nasional Berhad installed a 100 MW solar farm on top of the Manjung power station's floating coal ash pool. The company was using this installation as a pilot and may repeat the process at other coal-fired power plants.[19]
